I was thinking of getting AFR heads later down the line with a cam and trick flow intake. I know that the AFR 225 flow a lot more than the 165, but would it be worth the money to get the 225's?
If you plan on doing a lot of street driving and limited track action, I would go with the 185s I have seen a lot of good numbers out of those heads and they can excel at the track also. The 225s are a deep breathing set of heads and you would probably need a steep set of gears, and a stout cam to complement them. Hope this helps you a little.
165's are fine for the street. WIth the 185's you have to notch your pistons. the 165's ported will get you into the 11's NA if you have a good enough combo.
So if i was to go with the 185's i would have to buy new pistons or get the ones i have machined? What is a good intake to run with the AFR's or does it not matter... Or should i just consider running the Trick flow twisted wedge heads with trick flow intake? Thanks boys:beer:
